Pro Sites menu will not display?

Support Access has been granted.

I can't get the Pro Sites menu to display in the dashboard for logged in users.
I have the Membership plugin and I am trying to control which membership levels have access to Pro Sites. When I go in to manage any the membership levels I do not see the Pro Sites option in the main menu rules.

What am I missing here?
